Extended ESG information
This section provides supplementary sustainability information that complements our annual reporting and offers additional context on our ESG performance and commitments.
Circularity and resource management
ASM is committed to promoting a more circular economy. In this sustainable production model, we see long-term opportunities for ASM in operations, product design, logistics and packaging, and building design.
For example, we are focusing on responsible resource consumption. This is a direct way to reduce materials usage and reduce greenhouse gas emissions. Ultimately, our ambition is to eliminate all waste through avoidance, reuse, or recycling. Where we encounter challenges – such as limited regional capabilities for recycling or reclaiming or the mandatory mixing of waste streams for regional sorting – we apply our passion for innovation and collaboration to help develop a better approach.
We track and account for all waste generated at our production and engineering sites. In 2025, we achieved a 81% recycling and reuse rate for non-hazardous solid waste across ASM operations.

ASM prioritizes minimizing hazardous waste generation and managing hazardous waste responsibly. In 2025, our global operations generated 9 metric tons of hazardous waste, comprising 2.1 metric tons recycled or reused and 6.9 metric tons disposed. The hazardous waste data has been subject to independent limited assurance. The table below provides a breakdown for total hazardous waste in metric tons from 2021 to 2025.

Environmental management system
We are certified globally to the ISO 14001 environmental management system (EMS), including all our primary engineering and manufacturing locations.
This EMS ensures that we are consistent in our operations and provides a foundation for best practices to be shared and learned across our sites. Read on to discover our practices and policies across different aspects of our sustainable operations.
Diversity composition
ASM monitors racial and ethnic self-identification data where legally permitted and voluntarily disclosed by employees. Employees with known racial and ethnic self-identifications represent more than 50% of ASM's global workforce. This data is used to understand workforce composition and representation in management positions and to support diversity, equity and inclusion efforts. As of 2025, the distribution of employees with known racial and ethnic self-identifications is shown in the table below.
| Racial and ethnic self-identifications | Share in workforce* | Share in management positions* |
| Asian | 59% | 50% |
| Black or African American | 2% | 1% |
| Hispanic or Latino | 5% | 3% |
| White | 28% | 44% |
| Indigenous or Native | 1% | 0.4% |
| Two or more ethnicities/Others | 6% | 3% |
* Percentages may not total 100% due to rounding.
Government affairs
Governance and oversight
ASM’s Government Relations function is part of the CEO organization, ensuring direct executive oversight of all public policy activities. The head of Government Relations coordinates advocacy efforts globally supported by regional government affairs leads. This structure provides accountability at the highest level and promotes consistent aligned messaging across all regions. ASM engages with public stakeholders both directly and through collaborations, including participation in industry associations and other stakeholder consultation bodies. These combined efforts strengthen our ability to advance ASM’s strategic objectives in a responsible and coordinated manner.
Review and alignment process
ASM has robust internal processes to review and monitor our own and industry association advocacy activities for alignment with our company policies including our commitment to the net-zero and other sustainability targets. On at least an annual basis, we evaluate our direct advocacy positions and our associations’ public policy stances. This regular review ensures that ASM’s participation continues to be beneficial and aligned with our commitments.
If ASM identifies a misalignment between our sustainability commitment and that of an industry association or their advocacy activity, we take case-by-case action to address it. This includes actively engaging with the association’s leadership or the relevant working group to communicate our positions. If an organization were to adopt a position or undertake lobbying contrary to our sustainability commitments and if our engagement efforts do not resolve the issue, ASM assesses other viable actions. This could include withdrawing our support, abstaining from that specific initiative, or, if necessary, ending our membership or involvement in the association.
ASM did not make any contributions to political campaigns, political candidates, or lobbying organizations in the 2021–2025 reporting period.
Performance through trusted ratings
ASM engages with several leading ESG rating agencies to support transparency and continuous improvement in our sustainability performance. These include CDP for Climate Change and Water Security, S&P Global CSA, Sustainalytics, MSCI ESG, ISS ESG, and FTSE Russell. Each provides an independent perspective on how we manage environmental, social, and governance topics. These assessments help us benchmark our progress, identify areas for improvement, and align with the expectations of our stakeholders. They also support our efforts to create long-term value and reinforce our commitment to responsible and sustainable business practices.
